The phrase "a flat core" is correct and usable in written English.
It can be used in contexts where you are describing an object, concept, or structure that has a flat central part or essence.
Example: "The design of the new speaker features a flat core that enhances sound quality and reduces distortion."
Alternatives: "a level center" or "a flat center".
He argues that the declines in rents, lodging away from home and apparel, which tipped the balance toward a flat core reading rather than a 0.1% reading, will persist.
Based on the unique mechanical characteristics of the pinned ABRBs, a design method applicable for the pinned ABRB with a flat core is put forward, considering the external restraining stiffness reduction coefficient and the additional local influence of contact force when the core deforms in a multi-wave form.
N-body simulations in the standard cold dark matter (CDM) model predict the dark matter distribution shows a cuspy dark matter profile: ρ(r) ∝ rα, with α in the range 1 2, while observations of dwarf and low surface brightness galaxies seem to favor the presence of a relatively flat core: 0 < α < 1.
Early on May 9, a Hurricane Hunters flight into the system revealed winds of 45 mph (70 km/h) and a flat thermal core, which indicated the system was neither warm-core nor cold-core.
Even if it is empirically clear that a suitable combination of a flat, aromatic core, and a number of laterally attached alkyl chains may result in spontaneous mesomorphic behaviour, a large body of observations remains unexplained.

The June flat core (Fig. 7) was also mostly sulfidic, with ΣH2S reaching 2 mM.
ΣH2S dominated the March flat core (Fig. 6), though traces of other analytes were occasionally visible.
While the February flat core (Fig. 5) most closely resembled the February bank core (Fig. 1), extensive porewater ΣH2S accumulation, and hence SO42- reduction, were observed in the March flat core (Fig. 6).
